RICHARD ALIIFII REV", OF MANKATO, MINNESOTA.

VENTILATING IVl ECHANlSll/l.

SPECIFICATION forming part of Letters Patent No. 399,437, dated March 12, 1889.

Application tiled March 29, 1 8 8 8.

To (.277, wmnb 'it 71mg/ conce/m lle it known that I, l'iIcHARD ALLEN REW, a citizen of the IInited States, residing at Mankato, in the county ot Blue Earth and State of Ilflinnesota, have invented new and useful Improvements in YVentilating Mechanism, ot.' which the following is a speciiication.

The invention relates to improvements in ventilating mechanism attached to buildings made in compartments, the object being to provide means whereby the cold pure air admitted into the separate rooms shall be admitted from above the windows or adjacent to the ceiling and mix with the warm air ris ing thereto, while the foul or impure air shall be carried (,rlt rom near the floor; and it consists in the construction and novel combina; tion ot" parts hereinafter described, illustrated in the drawings, and pointed out in the claims.

In the drawings, Figure I is a horizontal section of a building having stories of two rooms, each with the ventilating apparatus applied thereto. Fig. 2 is avertical sectional view showing the construct-ion and arrangement ot' the horizontal air-tlues adjoining the Hoor, the sections being closed. Fig. 3 is a similar view, the sections being open. Figs.

et, 5, and (3 are vertical sections ot' windows of different styles, to which modifications of the invention have been applied.

Referring to the drawings byletter, A A designate two adjoining rooms separated bythe wall or partition (t and having the iixed mopboard or skirtin g I3, adjoining the floor, and the molding l), secured to and standing outward from the top ol' said mop-board and stayed in place by the brace-rods b o.

C C are hinged sections depending from the free edge oi' the molding and Vclosing against the upper edge oli' the plaiiking C, standing ed gewise t' romV the flooring a proper distance from the walls, the meeting edges of said sections and said. planking being correspoildingly beveled to cause the former to bear closely against thelatter when closed, so as to make a close joint.

I) l) are adjusting bolts or screws the ends of which engage tapped openings in the mopboard, and by means of which the sections C may be closed air-tight or opened to any de sired extent.

sean No. 268,729. (no maar The meeting edges ot' the hinged sections() and the vertical planking C are preferably lined with rubber or feltin g tomalce the joints between closer, and an adjusting-bolt and seetion are preferably placed below each window and adjacent to each door, so thatin cold weather the cold layer et air formed by the glass rendered cold by the outside air, or the cold air coming in through the door when opened, can be immediately allowed to escape through the li ues d, formed by the mop-board and hinged sections.

E E are vertical air-escape lines rising from the basement to a suitable height above the house and communicating with the lines d in each story. The said vertical liues may be arranged in the corners of the rooms, it desired, or at the ends or sides, and may either be built with the house or added thereto.

e c are valves in the llues d, which are prefe ably arranged over or adjacent to the communicating openings between said tlues and the vertical llues E, and also adjacent to the separating-partition a between the rooms, so that the lines (l in one room can be cut ott' from those of the other, and the said lines can be cut oit from the vertical. Il ues; or the valves may be more or less opened to regulate the force and volume ot the air-circulation.

The levers and linlcrods are situated to one side of the tine, andthe tlueatthe place where a register is situated has twice its usual transverse area, the register, when it is entirely open, occupies one-half the transverse area at the place where it is situated, as the size ot' its bars and slots are the same.

lll M are the windows, of which fm m are the upper and outer and Im ym. the lower and inner sashes.

rl`he cold pure air from the outside is allowed to iiow into the `room over the top of the upper sash above the curtain bracket and fixture. The upper sash is pulled down a suitable distance (see Fig. 5) and the air passes thereover into the room adjacent to the ceiling.

In Fig. i it is shown as coming directly into the room; but in Fig. 5 it passes up into the chamber N above or in the upper part of the windowframe through the screen therein, which cleans it oi' dust, and passes into the line O between the ceiling and the `lloor of the IOO room above, and iiows out of openings in the rosette l), at or near the center of the ceiling p.

Fig. 5 also shows the window-frame as having a lambrequin bracket or molding and three curtains. The said bracket is preferably attached to the top of the upper sash, as shown. Fig. 6 shows the air as flowing out of n the chamber N into a chamber, Q, made below the ceiling and having the perforations q for the escape of air.

A rubber closing-strip is attached to the bottom of the lower rail of the upper sash and projects against the glass ofthe lower sash to keep out insects, air, and dust.

The apparatus as described introduces into a room all the air desired in an easy, cheap, and most convenient manner, as the introduced airis mixed in small jets with the warmest air in the room near the ceiling and then gradually descends, the current being from above, below, and then out at the iioor-level through the iiues d to the vertical lues E.

Having described my inventioml claiml. The combination, in a house-ventilator, of the wall having the vertical escape-flue E, the mop-board arranged at a slight distance from the inner side of the wall on the floor, the molding h, connecting the upper side of the mop-board with the wall, and thereby forming a chamber, (l, communicating with the lower end of ue E, the door or valve C, hinged at its upper edge to the n1op-board and fitting snugly in an opening in the same, and the adjusting screw or bolt D, having its inner end engaging an opening in the side of flue E, and having its outer end swiveled in the door or valve, substantially as described.

2. The combination, with the window-frame having the upper and lower sashes, of the chamber N in the upper part ot' the frame connnunicating with the outer air, the chamber Q. below the ceiling and having the airperforations q in its lower side, said chamber Q communicating with chamber N, substantially as described.

In testimony that l claim the foregoing as my own l have hereto afiixed my signature in presence of two witnesses.
